Generated from the same geometry the printer is handed — the plate seen from directly above. It cannot show the relief, which is the part you have to hold.
The French Broad
Older than the mountains it runs through
This is the western North Carolina mountains at the scale you would walk them. The relief is the most dramatic in the collection relative to its size: the plate covers ground that rises from valley floors to the highest peaks in the eastern United States, and the exaggeration is set so a fingertip can read the difference. The Swannanoa piece, the small one on the east side, is the valley Asheville sits in — and it is the subject of its own puzzle.
What a child works out
- A single valley is made of smaller valleys, all the way down.
- Where two pieces meet, you are touching a ridge you could stand on.
- The shape of a town's watershed is the shape of the ground its weather runs off.

Zoom in, zoom out
A piece of each of these is the subject of the next one. Each plate is redrawn at its own scale, so it is a real map at every level rather than an enlargement of the one above.
